Hello Crocodile; Let's start with an explanation of how the S7-400 memry is divided, and what external support cards can be used as Load memory: How can I get an overview of the S7-400 memory concept? As you can see, Load memory can use internal RAM, extended with a RAM memory card, or a Flash (EEPROM) memory card. The Flash card requires no battery support, and will be loaded with the PLC program, as seen here:How can you write the program to the FLASH Memory Card when using a SIMATIC S7-400 CPU? If you use a large enough Flash memory card, you can also use it to store documents and drawings pertinent to your project, or a full archive of the program if you want operators to retrieve it from a safe location at a much later date after you have left the project.How can you also store other files that belong to the project or plant on the MC/MMC? Hope this helps, Daniel Chartier |
